Zero Air for Gas Chromatography

Pages 2 Pages

Background: Flame ionization detection (FID), a com- monly used detection technique for gas chromatography which involves passing a separated sample through a hydrogen-air ? ame to ionize a sample, is considerably more sensitive than thermal ionization for a broad range of compounds. FID is typically used to detect volatile organic compounds to nanogram levels. The air for the ? ame is added to the detector after the separation and the
